Suture Granoloma Mimicking Bladder Stone: A Diagnostic Challenge

Abstract

Bladder stones are a rare complication of urinary stones, with a higher prevalence in male patients. They can be categorized as primary or secondary, with secondary bladder stones often associated with underlying conditions such as bladder outlet obstruction, urinary tract infections, and foreign bodies. This case report presents the surgical intervention for a 27-year-old woman with a history of mental retardation and asthma who presented with urinary incontinence and other urinary symptoms. Imaging confirmed the presence of a large bladder stone attached to a nylon suture string. The stone was successfully fragmented and removed, and the suture material was cut and extracted. Follow-up showed resolution of symptoms, and the patient was discharged with appropriate medication. This study highlights the association between bladder stones and foreign bodies, particularly suture materials used in vesicle surgeries. Previous studies have reported bladder stone formation related to both absorbable and non-absorbable sutures. This emphasizes the need for further research to investigate preventative measures and the choice of suture materials to minimize the risk of bladder stone formation. It is important for clinicians to be aware of this potential complication when performing bladder surgeries and to consider alternative suturing techniques or materials to reduce the risk of stone formation.
